Question

Brine, a concentrated aqueous salt solution, is frequently applied to the roads to pre-treat when snow is forecasted. It is known to be more effective when compared with solid ice melting products. Based on your understanding of the concept of freezing point depression, select all the reasons that explain why it is better to use the anti-icing agent brine than using solid ice melting products. It will be helpful to think about storage and dispersion when taking costs into account for the brine and solid ice melting products.
a. Applying brine on roadways accelerates the melting process because salt needs to be moist to be effective.
b. Solids may lead to land pollution while brine does not.
c. Snow storms sometimes start as rain which may wash away the solid ice melting products.
d. The salt in brine sticks to the roadway after the water part evaporates preventing the salt from being blown off by vehicles driving on the road.
e. The cost per ton is higher for solid ice melting products than it is for brine

Answer 1

Answer:

Applying brine on roadways accelerates the melting process because salt needs to be moist to be effective.

The cost per ton is higher for solid ice melting products than it is for brine

The salt in brine sticks to the roadway after the water part evaporates preventing the salt from being blown off by vehicles driving on the road.

Snow storms sometimes start as rain which may wash away the solid ice melting products

Explanation:

Brine is a concentrated salt solution used to remove ice from roads during winter. It functions by lowering the melting point of ice. Since brine is a solution, it works faster and accelerates the melting process because brine needs to be moist to be effective.

Similarly, it does not easily wash off roads as solid melting products does. It tends to stick better on roads even after the water evaporates.
